Could be exposure (percentage-wise) mode of action plays a part as well as possible resistance; if any. For example, some are stomach poisons ingested by bugs that groom & will not absorb through their bodies. Since a spider has no antennae to keep clean, these won't do much for them.

Is tangan-tangan effective as pesticide?
Tangan-tangan, or the plant Acanthospermum hispidum, has been traditionally used in some cultures for its pesticidal properties. Research indicates that extracts from this plant can exhibit insecticidal activity against certain pests, making it a potential natural pesticide. However, its effectiveness can vary based on factors such as concentration, application method, and target pests. Overall, while it shows promise, more extensive studies are needed to fully establish its efficacy and safety as a pesticide.
A researcher sprays a new pesticide on thousands of insects of the same species that live in a large field a few of the insect survive what can be concluded by the researcher?
The researcher can conclude that a small percentage of the insects possess traits that confer resistance to the new pesticide. This could indicate a genetic variation within the population that allows some individuals to survive despite the pesticide application. Further investigation would be necessary to understand the mechanisms of resistance and the implications for future pesticide use.
What are causes of pesticide overuse?
Pesticide overuse is primarily driven by the desire to maximize crop yields and protect against pests, often due to economic pressures on farmers. Additionally, the lack of integrated pest management practices and reliance on chemical solutions can lead to excessive application. In some cases, inadequate education on safe pesticide use and regulatory oversight can contribute to overuse. Lastly, the persistence of pests and the emergence of resistance may prompt farmers to apply more pesticides in an attempt to maintain effectiveness.
Tips On Removing Pests ?
Many different varieties of pests can make their way into your home. Anything from mice or rats to spiders and wasps. These pests can cause damage to your food supply and possibly your health or your home. You can exterminate pests around your home using some basic supplies and insect pesticide. Start by figuring out where pests are entering your home and block off the areas. Set traps if necessary and apply insect pesticide to the area. Finish the area by cleaning up any food scraps or other items that could encourage pests to settle. Maintain the cleanliness and apply insect pesticide in regular intervals to keep pests at bay.
What factors influence the effectiveness of a pesticide rain light wind?
The effectiveness of a pesticide can be influenced by factors such as the timing of application in relation to rain, as rain can wash away the pesticide before it has a chance to work. Light can affect pesticide breakdown rates and efficacy, with some pesticides being degraded by sunlight. Wind can also impact the application of pesticides, as it can cause drift and uneven distribution of the pesticide.
Who invented pesticides?
Since a pesticide can control even spoilage of food, the inventor of the pesticide would have to be that first human who discovered that application of salt made some foods such as fish and or meats last much longer.
IS malathion a contact pesticide or systemic?
Malathion is primarily a contact pesticide, meaning it acts on pests when they come into direct contact with it. It can also exhibit some systemic properties, allowing it to be absorbed by plants and affect sap-sucking insects that feed on them. However, its main mode of action is through contact.
Do you spary vegables?
Yes, vegetables are often sprayed with pesticides to protect them from pests and diseases during their growth. However, it's important to wash vegetables thoroughly before consumption to reduce any pesticide residues. Some farmers also use organic methods, which may involve less or no pesticide use. Always check for local regulations and practices regarding vegetable farming and pesticide use.
What are the advantages and disadvantages of integrated pest management?
Some of the benefits of Integrated Pest Management is that the decrease of the use of chemical application reduces the risk of bad side effects to staff, results in the saving of money and decreases the risk of property damage from the chemicals used.
When a pesticide is sprayed and there are still survivorswhat can you assume about them?
When there are survivors after a pesticide is sprayed, it can be assumed that these individuals possess some level of resistance or tolerance to the active ingredient in the pesticide. This resistance may arise from genetic variations that allow them to survive exposure. Additionally, the survivors could have been in microhabitats where the pesticide concentration was lower or they may have behaviors that enabled them to evade the spray. Over time, these resistant individuals can contribute to a population that may become increasingly difficult to control with the same pesticide.
Where did pesticide come from?
The first pesticides were probably phytotoxins, chemicals produced by plants to discourage insect infestation. The term "pesticide" simply describes how a chemical is used, not what it's made of. For example, the infamous Zyklon-B that the Nazis used in their death camps was manufactured as a pesticide.
What organizations do not welcome pesticide bans?
Organizations such as agricultural industry groups, pesticide manufacturers, and certain farmer associations often do not welcome pesticide bans. They argue that pesticides are essential for ensuring crop yields, controlling pests, and maintaining food security. Additionally, some research institutions and trade organizations may oppose bans due to concerns over economic impacts and the potential for increased pest resistance. These groups typically advocate for regulated pesticide use rather than outright bans.
